    NOTICE:
    1. Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.
    2. When measuring the resistance, the temperature of the sensor and the cooler thermistor must be the same.
    HINT:
    As the temperature increases, the resistance decreases (see the graph).
    If the operation is not as specified, replace the cooler thermistor.
